Subject: [PATCH 01/13] Implement layered environment configuration system
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add layered .env file structure (.env, .env.development, .env.production)
- Environment automatically selected based on git branch via .envrc
- Base config in .env (no secrets)
- Development config with test Turnstile keys
- Production config with placeholders
- All secrets moved to .env.local (not committed)
- Update wrangler.toml with environment-specific configurations
- Add comprehensive documentation in .env.README.md
- Update .gitignore to allow base config files while keeping secrets ignored

Loading order: .env → .env.$ENV → .env.local
Branch mapping: dev/develop → development, main/master → production

+# Environment Configuration
+
+This project uses a layered environment configuration system powered by `.envrc` and `direnv`.
+
+## How It Works
+
+Environment variables are loaded in the following order (later files override earlier ones):
+
+1. **`.env`** - Base configuration shared across all environments (committed to git)
+2. **`.env.$ENV`** - Environment-specific configuration (committed to git)
+3. **`.env.local`** - Local overrides and secrets (NOT committed to git)
+
+The `$ENV` variable is automatically determined by your current git branch:
+
+| Git Branch | Environment | Loaded File |
+|------------|-------------|-------------|
+| `main` or `master` | `production` | `.env.production` |
+| `dev` or `develop` | `development` | `.env.development` |
+| Other branches | `local` | `.env.local` |
+| Custom branch with file | Custom | `.env.$BRANCH_NAME` |
+
+## File Structure
+
+```
+.env                  # Base config (PORT, COMPILER_VERSION, etc.)
+.env.development      # Development-specific (test API keys, local DB)
+.env.production       # Production-specific (placeholder values)
+.env.local            # Your personal secrets (NEVER commit this!)
+.env.example          # Template showing all available variables
+```
+
+## Setup Instructions
+
+### 1. Enable direnv (if not already installed)
+
+```bash
+# macOS
+brew install direnv
+
+# Add to your shell config (~/.zshrc)
+eval "$(direnv hook zsh)"
+```
+
+### 2. Allow the .envrc file
+
+```bash
+direnv allow
+```
+
+You should see: `✅ Loaded environment: development (branch: dev)`
+
+### 3. Create your .env.local file
+
+```bash
+cp .env.example .env.local
+```
+
+Then edit `.env.local` with your actual secrets and API keys.
+
+## What Goes Where?
+
+### `.env` (Committed)
+- Non-sensitive defaults
+- Port numbers
+- Version numbers
+- Public configuration
+
+### `.env.development` / `.env.production` (Committed)
+- Environment-specific defaults
+- Test API keys (development only)
+- Environment-specific feature flags
+- Non-secret configuration
+
+### `.env.local` (NOT Committed)
+- **ALL secrets and API keys**
+- Database connection strings
+- Authentication tokens
+- Personal overrides
+
+## Wrangler Integration
+
+The `wrangler.toml` configuration supports environment-based deployments:
+
+```bash
+# Development deployment
+wrangler deploy --env development
+
+# Production deployment
+wrangler deploy --env production
+```
+
+Environment variables from `.env.local` are automatically available during local development (`wrangler dev`).
+
+For production deployments, secrets should be set using:
+
+```bash
+wrangler secret put ADMIN_KEY --env production
+wrangler secret put TURNSTILE_SECRET_KEY --env production
+```
+
+## Troubleshooting
+
+### Environment not loading?
+
+```bash
+# Re-allow the .envrc
+direnv allow
+
+# Check what's loaded
+direnv exec . env | grep DATABASE_URL
+```
+
+### Wrong environment?
+
+Check your git branch:
+```bash
+git branch --show-current
+```
+
+The `.envrc` automatically maps your branch to an environment.
+
+### Variables not available?
+
+Make sure:
+1. You've created `.env.local` from `.env.example`
+2. You've run `direnv allow`
+3. The variable exists in one of the .env files
+
+## Security Best Practices
+
+- ✅ **DO** commit `.env`, `.env.development`, `.env.production`
+- ✅ **DO** use test/dummy values in committed files
+- ✅ **DO** put all secrets in `.env.local`
+- ❌ **DON'T** commit `.env.local` or `.envrc`
+- ❌ **DON'T** put real secrets in any committed file
+- ❌ **DON'T** commit production credentials
+
+## Environment Variables Reference
+
+See `.env.example` for a complete list of available variables and their purposes.

+# GitHub Actions Environment Setup
+
+This project uses a layered environment configuration system that automatically loads variables based on the git branch.
+
+## How It Works
+
+The `.github/actions/setup-env` composite action mimics the behavior of `.envrc` for GitHub Actions workflows:
+
+1. Detects the environment from the branch name
+2. Loads `.env` (base configuration)
+3. Loads `.env.$ENV` (environment-specific)
+4. Exports all variables to `$GITHUB_ENV`
+
+## Branch to Environment Mapping
+
+| Branch Pattern | Environment | Loaded File |
+|----------------|-------------|-------------|
+| `main`, `master` | `production` | `.env.production` |
+| `dev`, `develop` | `development` | `.env.development` |
+| Other branches | `local` | `.env.local` (if exists) |
+| Custom branch with file | Custom | `.env.$BRANCH_NAME` |
+
+## Usage in Workflows
+
+### Basic Usage
+
+```yaml
+steps:
+  - uses: actions/checkout@v4
+  
+  - name: Load environment variables
+    uses: ./.github/actions/setup-env
+  
+  - name: Use environment variables
+    run: |
+      echo "Compiler version: $COMPILER_VERSION"
+      echo "Port: $PORT"
+```
+
+### With Custom Branch
+
+```yaml
+- name: Load environment variables for specific branch
+  uses: ./.github/actions/setup-env
+  with:
+    branch: 'staging'
+```
+
+### Access Detected Environment
+
+```yaml
+- name: Load environment variables
+  id: env
+  uses: ./.github/actions/setup-env
+
+- name: Use detected environment
+  run: echo "Running in ${{ steps.env.outputs.environment }} environment"
+```
+
+## Environment Variables Available
+
+After loading, the following variables are available:
+
+### From `.env` (all environments)
+- `COMPILER_VERSION` - Current compiler version
+- `PORT` - Server port (default: 8787)
+- `DENO_DIR` - Deno cache directory
+
+### From `.env.development` (dev/develop branches)
+- `DATABASE_URL` - Local SQLite database path
+- `TURNSTILE_SITE_KEY` - Test Turnstile site key (always passes)
+- `TURNSTILE_SECRET_KEY` - Test Turnstile secret key
+
+### From `.env.production` (main/master branches)
+- `DATABASE_URL` - Production database URL (placeholder)
+- `TURNSTILE_SITE_KEY` - Production site key (placeholder)
+- `TURNSTILE_SECRET_KEY` - Production secret key (placeholder)
+
+**Note**: Production secrets should be set using GitHub Secrets, not loaded from files.
+
+## Setting Production Secrets
+
+For production deployments, set secrets in GitHub repository settings:
+
+```yaml
+env:
+  CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+  ADMIN_KEY: ${{ secrets.ADMIN_KEY }}
+  TURNSTILE_SECRET_KEY: ${{ secrets.TURNSTILE_SECRET_KEY }}
+```
+
+Required secrets for production:
+- `CLOUDFLARE_API_TOKEN` - Cloudflare API token
+- `CLOUDFLARE_ACCOUNT_ID` - Cloudflare account ID
+- `ADMIN_KEY` - Admin API key
+- `TURNSTILE_SITE_KEY` - Production Turnstile site key
+- `TURNSTILE_SECRET_KEY` - Production Turnstile secret key
+
+## Example: Deploy Workflow
+
+```yaml
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v4
+      
+      - name: Load environment variables
+        id: env
+        uses: ./.github/actions/setup-env
+      
+      - name: Deploy to environment
+        run: |
+          if [ "${{ steps.env.outputs.environment }}" = "production" ]; then
+            wrangler deploy --env production
+          else
+            wrangler deploy --env development
+          fi
+        env:
+          # Production secrets override file-based config
+          CLOUDFLARE_API_TOKEN: ${{ secrets.CLOUDFLARE_API_TOKEN }}
+          ADMIN_KEY: ${{ secrets.ADMIN_KEY }}
+```
+
+## Comparison: Local vs CI
+
+| Aspect | Local Development | GitHub Actions |
+|--------|------------------|----------------|
+| Loader | `.envrc` + `direnv` | `.github/actions/setup-env` |
+| Detection | Git branch (real-time) | `github.ref_name` |
+| Secrets | `.env.local` (not committed) | GitHub Secrets |
+| Override | `.env.local` overrides all | GitHub env vars override files |
+
+## Debugging
+
+To see what environment is detected and what variables are loaded:
+
+```yaml
+- name: Load environment variables
+  id: env
+  uses: ./.github/actions/setup-env
+
+- name: Debug environment
+  run: |
+    echo "Environment: ${{ steps.env.outputs.environment }}"
+    echo "Branch: ${{ github.ref_name }}"
+    env | grep -E 'COMPILER_VERSION|PORT|DATABASE_URL' || true
+```
+
+## Security Best Practices
+
+1. ✅ **DO** use GitHub Secrets for production credentials
+2. ✅ **DO** load base config from `.env` files
+3. ✅ **DO** use test keys in `.env.development`
+4. ❌ **DON'T** commit real secrets to `.env.*` files
+5. ❌ **DON'T** echo secret values in workflow logs
+6. ❌ **DON'T** use production credentials in PR builds

Subject: [PATCH 03/13] Allow .envrc to be committed to repository

- Remove .envrc from .gitignore
- .envrc contains the environment loading logic needed for local development
- No secrets in .envrc - all secrets remain in .env.local (still ignored)

Subject: [PATCH 04/13] Remove obsolete worker/.envrc file

The root .envrc now handles all environment loading with proper
layered configuration. The worker/.envrc is no longer needed and
contained outdated hardcoded values.

Subject: [PATCH 08/13] Fix environment configuration issues from PR review

- Fix GitHub Actions setup-env to properly parse dotenv files (strip quotes, handle comments)
- Update .envrc to use direnv's built-in dotenv loader instead of custom function
- Update .env COMPILER_VERSION from 0.8.3 to 0.11.4 to match deno.json
- Remove DENO_DIR from base .env (breaks GitHub Actions on /app/.deno path)
- Fix .env.production to use empty placeholders for Turnstile keys
- Update .env.production documentation to clarify wrangler secret usage
- Fix wrangler.toml localConnectionString to use real connection string template
- Update .github/ENV_SETUP.md branch mapping table to match actual behavior
- Fix .env.README.md to clarify .envrc should be committed
- Update deno.json dev task to remove --env=.envrc flag (now handled by direnv)

+# Docker Configuration
+
+This project uses Docker and Docker Compose with the layered environment configuration system.
+
+## Quick Start
+
+### Development
+
+```bash
+# Build and run with development configuration
+docker compose up -d
+
+# View logs
+docker compose logs -f
+
+# Stop
+docker compose down
+```
+
+### Production
+
+```bash
+# Set production secrets as environment variables
+export ADMIN_KEY="your_admin_key"
+export TURNSTILE_SECRET_KEY="your_secret_key"
+export DIRECT_DATABASE_URL="your_database_url"
+export PRISMA_DATABASE_URL="your_prisma_url"
+export OPTIMIZE_API_KEY="your_optimize_key"
+
+# Build and run with production configuration
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+```
+
+## Environment Configuration
+
+The Docker setup integrates with the layered `.env` file system:
+
+### File Loading Order
+
+1. **`.env`** - Base configuration (loaded by docker-compose)
+2. **`.env.${ENV}`** - Environment-specific (development or production)
+3. **Environment variables** - Passed via `docker-compose.override.yml` or `-e` flags
+
+### Environment Selection
+
+Set the `ENV` variable to control which environment file is loaded:
+
+```bash
+# Development (default)
+docker compose up
+
+# Production
+ENV=production docker compose up
+
+# Or use the production compose file
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up
+```
+
+## Configuration Files
+
+### docker-compose.yml (Base)
+
+The base configuration that works for all environments:
+- Defines service structure
+- Loads `.env` and `.env.${ENV}` files
+- Sets up volumes and networks
+- Configures health checks
+
+### docker-compose.override.yml (Development)
+
+Automatically merged in development, adds:
+- Source code volume mounts for live reloading
+- Development-specific settings
+- Template for local secrets
+
+### docker-compose.prod.yml (Production)
+
+Production-specific configuration:
+- Uses `.env.production`
+- Expects secrets from environment variables
+- Resource limits and constraints
+- Always-restart policy
+
+## Secrets Management
+
+### Development
+
+Option 1 - Use `.env.local` (recommended):
+```bash
+# Create .env.local with your secrets
+cp .env.example .env.local
+# Edit .env.local with actual values
+
+# Note: .env.local is excluded from Docker builds via .dockerignore
+# You need to pass secrets explicitly
+```
+
+Option 2 - Add to `docker-compose.override.yml`:
+```yaml
+services:
+  adblock-compiler:
+    environment:
+      - ADMIN_KEY=your_dev_key
+      - TURNSTILE_SECRET_KEY=your_dev_secret
+```
+
+### Production
+
+**Always use environment variables, never hardcode secrets:**
+
+```bash
+# Method 1: Export before running
+export ADMIN_KEY="production_key"
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up
+
+# Method 2: Pass inline
+ADMIN_KEY="production_key" docker compose -f docker-compose.yml -f docker-compose.prod.yml up
+
+# Method 3: Use a secrets file (not committed)
+echo "ADMIN_KEY=production_key" > .env.secrets
+docker compose -f docker-compose.yml -f docker-compose.prod.yml --env-file .env.secrets up
+```
+
+## Available Environment Variables
+
+### From `.env` (all environments)
+- `COMPILER_VERSION` - Compiler version
+- `PORT` - Server port (default: 8787)
+- `DENO_DIR` - Deno cache directory
+
+### From `.env.development`
+- `DATABASE_URL` - Local SQLite database
+- `TURNSTILE_SITE_KEY` - Test Turnstile key
+- `TURNSTILE_SECRET_KEY` - Test Turnstile secret
+
+### From `.env.production`
+- `DATABASE_URL` - Production database (placeholder)
+- `TURNSTILE_SITE_KEY` - Production site key (placeholder)
+- `TURNSTILE_SECRET_KEY` - Production secret (placeholder)
+
+### Required Secrets (production)
+- `ADMIN_KEY` - Admin API key
+- `TURNSTILE_SECRET_KEY` - Real Turnstile secret
+- `DIRECT_DATABASE_URL` - Postgres connection
+- `PRISMA_DATABASE_URL` - Prisma Accelerate connection
+- `OPTIMIZE_API_KEY` - Optimize API key
+- `WRANGLER_HYPERDRIVE_LOCAL_CONNECTION_STRING_HYPERDRIVE` - Hyperdrive connection
+
+## Docker Build
+
+### Build Arguments
+
+```bash
+# Build with specific Deno version
+docker build --build-arg DENO_VERSION=2.6.7 .
+
+# Build for specific architecture
+docker buildx build --platform linux/amd64,linux/arm64 .
+```
+
+### Multi-stage Build
+
+The Dockerfile uses multi-stage builds:
+1. **node-base** - Base image with Deno and Node.js
+2. **builder** - Installs dependencies and prepares files
+3. **runtime** - Minimal production image
+
+## Volume Mounts
+
+### Development (docker-compose.override.yml)
+```yaml
+volumes:
+  - ./src:/app/src          # Source code
+  - ./worker:/app/worker    # Worker code
+  - ./public:/app/public    # Static files
+```
+
+### Production
+```yaml
+volumes:
+  - deno-cache:/app/.deno   # Only Deno cache
+```
+
+## Health Checks
+
+The service includes a health check:
+```yaml
+healthcheck:
+  test: ['CMD', 'curl', '-f', 'http://localhost:8787/api']
+  interval: 30s
+  timeout: 3s
+  retries: 3
+  start_period: 5s
+```
+
+Check health status:
+```bash
+docker compose ps
+docker inspect adblock-compiler --format='{{.State.Health.Status}}'
+```
+
+## Troubleshooting
+
+### View logs
+```bash
+docker compose logs -f adblock-compiler
+```
+
+### Rebuild after changes
+```bash
+docker compose build --no-cache
+docker compose up -d
+```
+
+### Check environment variables
+```bash
+docker compose exec adblock-compiler env | grep -E 'COMPILER_VERSION|PORT|DATABASE_URL'
+```
+
+### Access container shell
+```bash
+docker compose exec adblock-compiler sh
+```
+
+### Remove all containers and volumes
+```bash
+docker compose down -v
+```
+
+## Security Best Practices
+
+1. ✅ **DO** use `.dockerignore` to exclude sensitive files
+2. ✅ **DO** pass secrets via environment variables in production
+3. ✅ **DO** use `.env.local` for local development secrets
+4. ❌ **DON'T** commit secrets to any Docker Compose file
+5. ❌ **DON'T** hardcode credentials in Dockerfile
+6. ❌ **DON'T** include `.env.local` in Docker builds
+
+## Example: Complete Production Deployment
+
+```bash
+#!/bin/bash
+# production-deploy.sh
+
+# Load secrets from secure storage (e.g., AWS Secrets Manager, Vault)
+export ADMIN_KEY=$(aws secretsmanager get-secret-value --secret-id prod/admin-key --query SecretString --output text)
+export TURNSTILE_SECRET_KEY=$(aws secretsmanager get-secret-value --secret-id prod/turnstile --query SecretString --output text)
+
+# Pull latest code
+git pull origin main
+
+# Build and deploy
+docker compose -f docker-compose.yml -f docker-compose.prod.yml build
+docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
+
+# Verify health
+sleep 10
+curl -f http://localhost:8787/api || exit 1
+
+echo "Deployment successful!"
+```
